 bounded by the temporal lines and terminating below the level of the zygomatic arch
Zygomatic arch
The zygomatic arch or cheek bone is formed by the zygomatic process of temporal bone and the temporal process of the zygomatic bone , the two being united by an oblique suture; the tendon of the Temporalis passes medial to the arch to gain insertion into the coronoid process...

.

Boundaries

  • Medial: Os frontale, os parietale, os temporale, os sphenoidale, os occipitale (bones of neurocranium).
  • Lateral: Temporal fascia
  • Anterior: Posterior surface of the frontal process of the zygomatic bone and the posterior surface of the zygomatic process of the frontal bone.
  • Superior: Pair of temporal lines (superior and inferior temporal lines) that arch across the skull from the zygomatic process of the frontal bone to the supramastoid crest of the temporal bone
  • Inferior: Zygomatic arch laterally and by the infratemporal crest of the greater wing of the sphenoid medially.
